The pH of water is a very important measurement concerning water quality.
Calcium+
0 to 100 mg/L
A level of 50 mg/L is recommended as the upper limit for drinking water.
Chloride
1mg – 10 mg/litre
Chloride in water may be considerably increased by treatment processes in which chlorine or chloride is used.
Magnesium+
12mg/L – 600 mg/L
Magnesium in water appears as hydrated ions, which are more easily absorbed than magnesium in food.
Bicarbonate
pH < 6.3
At pH 10.3, the bicarbonate ion concentration equals the carbonate ion concentration.
Sodium ion
